Meatball Sub Garlic Bread Pasta Bake: One-Pan Comfort Step-by-step instructions

Before you start

Before starting, gather all ingredients and equipment. Cook the penne in a large pot of salted boiling water until al dente, about 1 minute less than package directions. Drain and set aside. If using raw meatballs, brown them in a skillet over medium-high heat with a little olive oil until browned on all sides; they will finish cooking in the oven.

If using pre-browned or fully cooked meatballs, skip this step. Preheat the oven to 400°F (200°C). Prepare the garlic-parsley butter by melting it in a small saucepan or microwave. Cube the sourdough bread if not already cubed. Have the marinara and mozzarella ready.

Instructions

Pasta and Meatballs

1. 1Cook the Pasta and Prepare the Meatballs
   Bring a large pot of salted water to a boil. Cook the penne according to package directions until just shy of al dente, about 1 minute less than the recommended time. Drain well and return to the pot. Meanwhile, if using raw meatballs, brown them in a skillet over medium-high heat with a little oil until browned on all sides but not cooked through; set aside. If using pre-browned meatballs, skip this step.
   Look for Pasta is tender but still firm; meatballs are browned with a crust.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Undercooking the pasta slightly keeps it from turning mushy during the bake.
2. 2Combine Pasta, Marinara, and Meatballs
   In a large bowl or directly in the baking dish, toss the cooked penne with the marinara sauce. Nestle the browned meatballs into the pasta mixture, pressing them down slightly so they are partially submerged. Spread the mixture evenly in a 9x13-inch baking dish.
   Look for The pasta is coated in red sauce and the meatballs are nestled throughout.
   Tip Use a spatula to gently fold without breaking the meatballs.

After this phase, you should have a large pot of drained penne, a bowl of marinara, and browned meatballs on a plate. The pasta should be slightly undercooked, and the meatballs should have a nice brown crust. The kitchen will smell of garlic and herbs from the meatballs. Make sure the meatballs are not fully cooked through if they are raw; they will finish in the oven. If using pre-cooked meatballs, they are ready to go. This phase sets the foundation for the bake.

Assembling and Baking

3. 3Toss Sourdough Cubes in Garlic Butter
   In a mixing bowl, combine the sourdough cubes with the melted garlic-parsley butter. Toss well so every cube is coated. Set aside while preparing the topping.
   Look for The bread cubes are glossy and fragrant with garlic and parsley.
   Tip Use a spatula to gently fold without crushing the bread.
4. 4Top with Mozzarella and Garlic Bread Cubes
   Sprinkle the shredded mozzarella evenly over the pasta and meatballs. Scatter the garlic-butter sourdough cubes over the cheese in an even layer, covering the surface as much as possible.
   Look for The top is covered with cheese and bread cubes; some sauce may peek through.
   Tip Distribute the bread cubes evenly for crunchy bites in every serving.
5. 5Bake Until Bubbly and Golden
   Preheat the oven to 400°F (200°C). Bake the dish for 20 minutes, or until the cheese is melted and bubbly and the bread cubes are golden and crispy. If the bread cubes brown too quickly, loosely cover with foil for the last 5 minutes.
   Look for The cheese is fully melted with browned spots; the bread cubes are crunchy and golden.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip For extra crispiness, broil for 1-2 minutes at the end, watching closely.

By the end of this phase, the baking dish is assembled with the pasta, meatballs, marinara, mozzarella, and garlic-butter bread cubes on top. The dish goes into the oven and bakes for 20 minutes.

You'll see the cheese melt and bubble, and the bread cubes turn golden and crisp. The aroma of garlic and tomato fills the kitchen. Check that the bread cubes are not burning; if they are, cover with foil. The internal temperature of the meatballs should reach 160°F (71°C).

Resting and Serving

6. 6Rest and Serve
   Remove the baking dish from the oven and let it rest for 5 minutes. This allows the cheese to set slightly and makes serving easier. Scoop portions onto plates, making sure each serving includes a meatball, some cheesy penne, and a few crunchy bread cubes.
   Look for The bake is slightly set but still saucy; the bread cubes remain crunchy.
   Tip Use a large spoon or spatula to lift out portions without disturbing the topping.

After baking, the dish rests for 5 minutes. The cheese is set but still gooey, and the bread cubes are crunchy. When you scoop into the bake, you'll see stretchy cheese, juicy meatballs, and saucy penne. The top should be golden and inviting. Serve hot, ensuring each portion has a meatball, some pasta, and a few crispy bread cubes. The texture contrast is the highlight: crunchy on top, tender pasta, and moist meatballs.

Common mistakes

One common mistake is overcooking the pasta before baking, which can lead to a mushy casserole. Cook it just shy of al dente. Another pitfall is using too much sauce, which can make the dish soupy; the pasta should be well-coated but not swimming.

If the bread cubes are not tossed evenly in garlic butter, some may burn while others stay soft. Also, avoid using pre-shredded mozzarella that contains anti-caking agents, as it may not melt as smoothly. Finally, don't skip the resting time after baking; it helps the dish hold together when serving.

How to tell it’s done

The bake is done when the cheese is fully melted and bubbly, and the bread cubes are golden and crispy. To ensure the meatballs are safe to eat, insert an instant-read thermometer into the center of a meatball; it should read at least 160°F (71°C).

The pasta should be tender but not mushy, and the sauce should be bubbling around the edges. If the bread cubes brown too quickly, cover loosely with foil for the last few minutes. Let the dish rest for 5 minutes before serving to allow the cheese to set slightly, making it easier to scoop.

• Ground meat: 160°F (71°C) in the thickest part
• Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
